Palomo Spain designer Alejandro Gómez Palomo toldVogue in comments posted Friday that Beyoncé placed a personal order for the outfit after being sent loaner samples and that he and his team took her measurements, tailored the piece, and sent it back.

So, like the rest of the world, Alejandro was stunned by Bey's Thursday night upload, but for slightly different reasons.

"This is a really big surprise, obviously", says Palomo. It's just really lovely. "It's exquisite.and I can never find it again", Palomo says of the fabric he used to create the gown. "It had a midcentury quality-but we changed that [.] it's a gown, now, that nearly has the shape of a big fur coat-sleeved and open".
